LB = lock box
SC = servicing center
If your receipt number has 9 as the sixth digit then its likely gone to a lockbox. eg. MSC2391234567
if your receipt number is something like WAC2312151234 then its likely gone to a servicing center. WAC is the servicing center - 23 is the year - 121 is the computer working day number counted from Oct 1 - and last five digits are your USCIS case number.
